    • The spatial walk-off is defined as the lack of parallelism between the k vec vector and the Poynting vector; it occurs for extraordinary waves in birefringent media. In general, in phase-matching conditions, the walk-off prevents the Poynting vectors of idler, signal, and pump fields from having the same direction and, in the absence of parametric interaction, the beams from overlapping over a long path in the crystal. The group-velocity mismatch between pulses with different wavelengths and/or polarizations due to dispersion introduces a lap among the pulses which also limits the pathlength of overlap. Note that the modifications in beam and pulse profiles due to the parametric interaction affect the pathlength over which the interaction can occur.
